Application filed February 3, 1910. Serial Ho. 541,943.

To all whom it may concern:

Be it known that I, JOHN T; Sorraarr, citizen of the United States, andresident of Vashington, in the District of Columbia,

have invented certain new and useful Improvements in Type-WritingMachines, of which the following is a specification.

' My invention relates especially to tabulating mechanism fortypewriting machmes and the main object of said invention is'to providean improved and simple column selecting mechanism which enables thetraveling element or carriage to be released and moved to apredetermined one of a plurality of columnar positions, any interveningcolumnar positions being skipped or passed.

To the above and other ends my invention consists in the features ofconstruction, combinations of devices and arrangements of partshereinafter described and particularly pointed out in the claims.

One form of my invention is shown in the e accompanying drawings whereinclear understanding of said invention.

. cal sectional view taken on a plane represented by the dotted line 'z-g of Fig. l and looking in the direction of the arrows at said line.Fig. 4- IS an operating view of the column selecting mechanism. Figs. 5to S inclusive are fragmentary views showing the normal relation betweenthe various column selecting levers and the part moved by said leversand controlling the variably movable frame stop. Fig. 9 is a perspectiveview of the column stop bar and column stops thereon. 1

In the various views parts are omitted and parts broken a\ my.

\Vhile my invention is shown adapted to a front-strike typewritingmachine of the Yost visible style, it is to be understood that saidinvention is applicable in whole or in part to other styles ofwritingmachin s i In the present instance the main frame of the machinecomprises side plates 1a a back plate 2, a fore top plate 3 and a. reartop plate 4, the top plate parts or sections being spaced apart toprovide room for a carriage comprising a truck 5 and a shiftable platenframe 6, which frame is connected with said truck by links 7 and carriesa platen 8. The truck 5 is provided with grooved rails. 9 whichcooperate through anti-friction balls 10 with fixed grooved track-ways11. The carriage is connected by a band 12 with a spring drum 13 pivotedon brackets 14 depending from a stationary frame bar 15. Said springdrum constantly urges the carriage leftward, leftward motion beingcontrolled by devices including a horizontal feed rack 16 supported byarms 17 pivoted to the carriage at 18 and depending from the undersidethereof so that the rack bar may be swung fore and aft of the carriage.The front edge of the rack bar is toothed and said rack bar is normallyheld in the Fig. 1 position by a spring-pressed plunger 19 on the truck5, said plunger pressing down on a branch 20 of an arm 17, the normalposition being determined by a stop pin 21 which cooperates with anotherbranch of said arm 17. The feed rack normally meshes with a pinion onthe upper end of a vertical shaft 2-l journaled on an arm 25 fixed tothe frame bar 15, the lower end of said shaft being journaled on anadjustable stud 2G threaded through an ear on astationary frame bar 27supported on the frame plates 1. The escapement wheel 28 is operativelyconnected with the shaft and is adapted to cooperate with the usual orsuitable feed dogs (not shown) which are controlled by printing andspacing keys. The shaft 2st carries a cylindrical housing 29 whichcontains or may contain pawl and ratchet mechanism, which, whileconnecting the escapement wheel with the shaftduring the advance of thecarriage left-ward, permits rotation of" the shaft independently of theescapement wheel during returnmovements of the car-' riage. The latter,of course, is normally under the control of the feeding or escape. 100

ment devices whereof the escapenient wheel, is an-element. i Themechanism for releasing the carriage comprises a shoe 30 formed on theupper end of a lever arm 31 secured to a. rock shaft 33 105 journaled ona bracket 3 depending from the frame bar 15, said shoe standing in frontof the feed rack 16. The rock shaft 33 has fixed to it a forwardlyprojecting arm 35 which is connected by a link 36 with the universal barof the column selecting mechanism, as presently to be described. Byraising the link 36 the shoe 30 is swung rearward, thereby disconnectingthe feed rack from the pinion.

The tabulating mechanism comprises a toothed stop bar 37 supported ontwo brackets 38 and 39 which are secured to the carriage truck 5 byscrews 40. The stop bar 37 is rectangular in cross section and isslidably mounted so that it may move to a limited extent lengthwise ofand relatively to the carriage for the purpose of diminishing the shockdue to the impact against a frame sto 3 of one of the column stopscarried by sai bar. The slidable mounting comprises a piston head 41fixed to the right-hand end of the stop bar 37 and cooperating with afixed cylinder 42, a coiled spring 43 being interposed between thepiston head and the head of the cylinder. The construction thus brieflydescribed is in the nature of a dash pot and is more fully set forth andis claimed in my co-pending application Serial No. 525,698, filedNovember. 1, 1909. The stop bar 37 is notched or toothed at its forwardand rear faces, the interdental spaces being a letter space distanceapart as is'common and adapted to receive adjustable column stops ofwhich four are shown in the resent.

instance and numbered from left to right 44,

' 45, 46 and 47. Each of these column stops comprises a notched orbifurcated sheet metal strip or plate having an angular stiffeningflange and which may be. arranged to straddle the stop bar 37 betweenthe teeth thereof at any desired point, said column stops ,being slippedon said stop bar from above. Each column stop has an edge portion bentoff at right angles to form a stiffening flange 48 and is provided witha depending portion or lug which constitutes the stop portion proper ofthe stop. T hose lugs are separately numbered. for convenience ofdescription as 4-11, 45, 46 and 47 As will be apparent from Figs. 1, 4and 9, they all terminate in a single horizontal plane but are out ofline with one another, each moving in a different path, all the pathsbeing parallel. In the present instance the lugs or stops proper are sodisposed that they leave an openspaec 3 directly beneath the stop bar,the stop lugs 44 and 46" being forward of said open space While stoplugs 45 and 47 a are back of the same.

Adapted to coiiperatc with the column stops is a frame stop or columnselecting stop in the form of a flat plate-like arm 49 which extendsupward through a hole in. the top plate 4 through a notch 50 in a guideplate 51 secured to the upper face of said top plate by screws 52. Thestop arm 49 is arranged edgewise in the direction of carriage travel andnormally its upper end or stopping portion lies in the open space orpathway .9 as best shown in Flg. 1 and so that a forward or rearwardmovement will bring it into the path of one or'another of the columnstop lugs. Thesto arm 49 extends downward, it bein slight y curved oroffset rearward and is etachably secured at its lower end by screws 53to a seat formed at the upper end of a lever frame 54, said frameinclining downward and forward and being pivoted on pivot screws 55which are supported on the arms of a bracket 56 fixed to and dependingfrom the frame bar 15. As best appears in Fig. 3 the lever frame isarranged between the arms of the bracket 56 and below the pivot screws55 is bifurcated to provide two branches or arms 57, said armsterminating at their lower ends in hubs which support a cross rod 58,said cross rod connecting the arms 57 of the lever frame.

The lever frame 54 and stop arm 49 are adapted, to be variablycontrolled through the cross rod 58 by column selecting levers of whichfour are shown in the present instance and numbered respectively '59,60, (i1 and 62. These column selecting levers are of thefirst order andare arranged side by side and'extend fore and aft of the machine, beingseatedin vertical notches or kerfs 63 formed in a lug or downwardextension 64- from the underside of the frame bar 27. 16ers 65projecting forward from the frame bar 27 are spaced apart as shown inFig. 2 and support pivot pins 66.which are secured in place by screws 67and proa vertical key stem 69, which is guided by.

fixed guide plates 70 and 71, each key stem terminating at the top in afinger key or.button 72. The keys 72 are arranged in a row above andbehind the lastrow of the regular set of keys and the top of each key 72may be suitably marked. 'As shown in Fig. 2 the top of the keyassociated with the lever. 59 is marked with the numeral 1, while the.

keys associated with the lovers 60, 61 and 62 f are marked respectivelywith the numerals 2, 3 and 4. The rear end portion of each of the columnselect ng levers where 1t underlies the cross rod 58 is widened somewhatas indicated at 73 and back of the widened portion 73 each lever isrovided with an upward extension or finger 4; which is bent rearwnrdiyat its top and has secured to it the upper end of a coiled restoringceases I rocked on its fulcrum, the rear arm of said lever being raisedso that it stretches the spring and lifts the upper edge of thethickened portion 73. of said'lever toward the cross rod 58. Said upperedge of each lever is formed with a cam slot, these cam slots varying indirection and inclination, as will be clear from Figs. 5 to 8 inclusive;

but the mouths of the cam slots being in line and normally underlyingthe cross rod 58 so that when raised separately they may engagetherewith. The cam slot 76 in the lever 59 inclines downward andrearward at such an inclination that when the lever 59 is operated andthe cam slot engages with the rod 58, it will cam. said rod rearward tothe extent shown by the dotted line position of said rod in Fig. 5. Thecam slot 77 in the lever 60 inclines oppositcly to the SlotT-G so thatsaid slot 77 is adapted to swing the cross rod 58 forward to the dottedline position in Fig. 6. The cam slot 78 in the lever 61 is directedrearward like the l cam slot 76 but ata lesser inclination, while thecam slot 79 in the lever 62 inclines forward but at a lesser inclinationthan the other forwardly inclined cam slot 77 so that itwill swing thecross rod 58 forward to a lesser degree. The construction is such thatthe cam sloti'ti will cotipcrate with the rod 58 to swing the leverframe 5. on its tul- .crum and throw the stop arm 48 forward into thepath of the column stop lug 44 The cam slot '78 will operate to throwthe stop arm a9 forward to a lesser extent and into the path of the stoplug 46 while the two cam slots 77 and 79 will operate to swing the stoparm ll) rearward different extents and so that it will cooperaterespectively with the column stop lugs 415*- and 47.

The. actuation of the column selecting levers not only variably actuatesthe stop arm 49 so as to move it different extents int-he arcuate pathtowhich it is confined, but.

also lifts the link 36 to effect the release of the carriage throughdevices comprising a bail-like universal bar men'iber 80 which overliesthe column selecting levers forward of the cam slots therein, saiduniversal bar rearwardly extending angular arm 80 is fixed centrally tothe universal bar frame 80 and is connected to a restoring spring 81anchored to the bracket After the detailed description of myimprovements heretofore given it is not deemed necessary to enter into afurther extended explanation of the mode of operation. In Fig. t theparts are shown in operative or abnormal positions resulting from theactuation of the fourth column selecting key which operates through thecam slot 79 to swing the stop arm 49 rear ard into the path of thecolumn stop lug 47 and also to release the carriage so that the same mayrun freely leftward until arrested by the.

co-action of the stop 49 with the stop lug 47, the stop 49 being heldlocked in co-acting position by the engagement of the bottom of the slot79 with the cross-rod 58 as long as the column keyis held depressed.During this leftward run the intervening column stop lugs whose pathsare not obstructed by the frame stop 49 will be skipped or passed. Itwill. lac-understood that a similar actuation of any of the other columnkeys will move the frame stop to a different extent and cause itsco-action with that one of the column stops which corresponds with theactuated column key. The arm has a cam notch which acts on the rod 58 toreturn the frame stop always to normal position and hold it therein.

It will be seen that my invention provides a simple and effective columnselecting mechanism which is rapid and certain in operation and which isadapted to v' ariousstyles of work, such for example, as writing in thedate, name and-address and thesalutation, etc, in letters, or the nameand address "on onvelops as well as for form or tabular work of variouskinds.
